It is commonly recognized that aspen (Populus tremuloides)
ecosystems in the Interior West provide numerous benefits: (1)
forage for livestock, (2) habitat for wildlife, (3) water for
downstream users, (4) esthetics, (5) sites for recreational opportunities,
(6) wood fiber, and (7) landscape diversity. Loss or potential
loss of aspen on these lands can be attributed primarily to the
successional process, reduction (or elimination) of fire, and
long-term overuse by ungulates. Western aspen forests are unique
because they reproduce primarily by suckering from the parent
root system.
